Re: Using externally calculated st.dev. in X by YYou can use --> Sample Index --> Teaching Scripts for a t-test with summary statistics:
But may be not appropriate for many rows.
Re: Using externally calculated st.dev. in X by YYou might also be able to use this solution.
You would have to run very many bootstrap samples to approach inference by resampling.
Re: Using externally calculated st.dev. in X by YI would probably use this graph to understand the data, mean on y and stddev as interval:
Resampling can be done of course, but will not lead to a good assessment with small differences.
Re: Using externally calculated st.dev. in X by YHi Mark,
thanks a lot! yes, this worked rather nicely, and so did the concatenation for categories that Ron mentions in his reply.
Re: Using externally calculated st.dev. in X by YHi Georg, thanks for this! Didn't know this option existed! Doesn't scale too greatly unfortunately.
The solution that Mark gave is what I was looking for! And, yeah, that's not a dataset with high effects...
Using externally calculated st.dev. in X by YHi everyone,
i occasionally get datasets, where there is no raw data available, just the mean, st.dev. and number of replicates. Is there a way to use this available data to run a t-test, for instance? A quick platform launch is included to show what I want to do.
I was thinking, that maybe constructing a simulated distribution (let's assume it's normal) with the given parameters and counts could be the way to go, but I I'm not sure how to do that. Does anyone have an idea? A scripted solution would be good, i could adapt that.
Have a great day!
